Carbon taxes are probably the most effective tool but politically unpalatable.

What's the advantage over the so far politically palatable carbon trading systems? Seems to me the end result is pretty much the same, except in carbon trading systems the market mechanism automatically adjusts the price to the available quota.

The advantage is that they work. Carbon trading schemes get watered down to the point that they are ineffective.
